Thanks for your response, I don't see any errors in both config.php files. I only have this problem when I click on products in admin and save modified product, what do you mean my update, thanks if you have more details

I'm not sure which you're reporting: that you had it using 'mysqli' and you changed it to 'mysql', or vice-versa. From the error messages you posted at the top, it sounds like maybe you were trying to use 'mysql' rather than 'mysqli'. I wouldn't be surprised if 'mysql' failed, as many hosts are no longer bothering to install the old MySQL library, preferring to install the newer MySQLi. Anyway, if you are now running MySQL instead of MySQLi, I would consider that only a temporary reprieve; you should be looking at updating your system so that you can use the newer (and supported) MySQLi.

OK, BUT, keep in mind that MySQL could disappear in your host's next PHP build, so you should be thinking about moving to MySQLi. These days it's quite unusual not to have MySQLi available on a server, in addition to (or even, instead of) the old MySQL. If your host doesn't have MySQLi at all, they may be quite behind the times. Just be aware.

I would have to totally agree here. MySQL server library has been deprecated since quite sometime by the Industry as it no longer recommended to be used within production PCI servers since this library is no longer compliant with RFC standards compared to MySQLi.
